RESUMO
En este trabajo revisamos los casos que hemos observado en los últimos diez años de enfermos tratados con hemodiálisis periódica que han recuperado la función renal en cuantía suficiente para poder interrumpir dicho tratamiento. Durante el período de estudio, 218 enfermos comenzaron tratamiento con hemodiálisis periódica en nuestro hospital y precisaron diálisis durante más de 90 días. En 17 de ellos (8%), se pudo interrumpir la diálisis, tras haber permanecido en ella un tiempo que osciló entre 95 y 529 días. La probabilidad de recuperación de la función renal fue mayor en los enfermos con nefropatía intersticial crónica (p = 0,04) o con enfermedades autoinmunes (p = 0,07), y en los que comenzaron tratamiento renal sustitutivo con dos sesiones de hemodiálisis a la semana (p = 0,02). No hemos observado diferencias significativas en edad, género, filtrado glomerular al inicio del tratamiento con hemodiálisis o índice de comorbilidad. Siete enfermos volvieron a precisar tratamiento con hemodiálisis tras un período de tiempo sin ella de 11 ± 7 meses. Dos enfermos fallecieron por motivos no atribuibles al tratamiento de la insuficiencia renal y otro salió del estudio por traslado a otro hospital tras haber permanecido 35 meses sin diálisis. Los 14 enfermos restantes están vivos y 8 permanecen libres de diálisis, con un tiempo de evolución que oscila entre 13 y 106 meses. Concluimos que la función renal residual no tiene por qué deteriorarse de forma inexorable tras el inicio de tratamiento con hemodiálisis, y que la posibilidad de recuperación funcional es factible en algunos enfermos (AU)
The aim of this study was to review all cases of recovery of renal function in chronic haemodialysis patients, observed in the last ten years. During the study period, 218 chronic renal failure patients were managed on haemodialysis for a minimum of 90 days. In 17 cases (8%), it was possible to interrupt dialysis after 95 to 529 days. The probability of renal function recovery was higher in patients with chronic interstitial nephritis (P=.04) or autoimmune diseases (P=.07), as well as in those starting haemodialysis treatment at a frequency of two sessions per week (P=.02). No significant differences in age, gender, glomerular filtration rate at the beginning of haemodialysis treatment, or comorbidity rate were observed. Seven patients returned to haemodialysis treatment after a dialysis-free period of 11±7 months. Two patients died for reasons unrelated to renal failure treatment, and another patient was moved to another hospital following 35 months without dialysis. The other 14 patients are alive and 8 are dialysis-free, with a monitoring period of 13 to 106 months. The conclusion reached is that there is no reason why residual kidney function should inexorably worsen after the start of haemodialysis treatment, and that functional recovery is possible in some patients (AU)
